We first establish a theoretical framework endogenizing firm's debt maturity with uncertain interest rates. We find that when the current short-term interest rate decreases compared with long-term rate (term spread increases), the expected future short-term rate increases. Hence, the relative cost of borrowing in short term increases at the current date but decreases at the rollover date. With these two opposite effects, the relationship between firm's optimal debt maturity and term spread can be hump-shaped. Then we use panel data of US firms from 1981-2018 to test our theoretical prediction. We regress firms’ debt maturity on term spread and term spread square. It is found that the coefficient of term spread (term spread square) is positive (negative) and significant, which implies a hump-shaped pattern consistent with our theoretical prediction. Robustness tests show that this empirical result is not driven by data pattern changes at different periods.
